A balanced chemical equation gives the actual number of each reactant that react with each other and the number of product molecules formed.
It is a fully detailed equation which gives the ratios between reactants and products. The above reaction is an example of a balanced chemical equation. It gives the decomposition of sodium oxide Na 2 O. When balancing the equation, we can use two methods: inspection method and the oxidation number method. Inspection method includes balancing the chemical equation by looking at the reactants and products. In this reaction, sodium oxide is the reactant, and it has two sodium atoms and one oxygen atom per molecule.
But on the product side, there is one sodium atom and two oxygen atoms. Therefore, first, we can add a stoichiometric coefficient to the reactant side; it is 2. Then, on the reactant side, there are four sodium atoms and two oxygen atom. Now the number of atoms in each side is equal; thus, we get a balanced chemical equation. Skeleton equation gives the types of reactants involved in the chemical reaction and the end products. However, this does not give the exact ratio between the reactants and products.
Therefore, the important details we can get from a skeleton equation are the reactants of the reaction, the products of the reaction and the direction of the reaction. For the above reaction, the skeleton reaction is as follows;.
